Procedure
50.96 g (0.247 mol) of 2,4-di-t-butylphenol, 28.84 g (0.272 mol) of methyl thioglycolate, 14.83 g (0.494 mol) of paraformaldehyde and 3.41 g of dimethylamine (33% in ethanol) are refluxed for 18 hours in 50 ml of DMF. The crude product (85.3 g) can, after working-up as described above, be further purified by flash chromatography. m.p. 55.0-55.5° C. Analysis for C18H28SO3 : calc. C, 66.63; H, 8.70; S 9.88%; found C 66.65; H 8.79; S 9.88%
